So i am blocked by this one number, i still text the number but sometimes it will say delivered but other times it will say nothing. does this mean i am getting unblocked and then blocked again or is it some type of glitch

You will have no way of knowing. Not sure if that would be a glitch or not. It is true that the Delivered message will not be consistent on your device if it is Blocked. It is also true that many times you will not see the Delivered message even if you are not blocked. This has more to do with that devices internet connection, DND, Airplane Mode, etc. It is clear that there is not 100% way to confirm you are blocked on another device, so it may be by design.
